Inter-and intramolecular hydrogen bonds in enamino thiones are compared with those in their 0x0 analogues (enamino ketones). While the efficacy as a proton-acceptor of the thione group in intermolecular hydrogen bonds is less pronounced than in the case of the carbonyl group the reverse is true with

Receveld 7 July 19e0, m fiial form 6 August 1980 Compounds wth mtramolecular hydrogen bonds are mvestlgated. When the hydrogen-bond donor and acceptor groups are not electromcally conjugated, IR contmua mdlcate a large proton polanzabibty. When they are ConJugated the contmua are very weak. Thus not
